Specification of Letters Patent.

Application filed June 6, 1910.

Patented Aug". 22", 1911. Serial No. 565,395.

To all whom it may concern:

Be it known that I ELMER E. HAUER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Strainers, of which the following is a specification, refer ence being had therein to the accompanying drawings.

My invention relates to strainers and more particularly to a strainer arranged so that the refuse caught by it can be removed without interrupting the flow of the fluid.

The object of my invention is to provide a strainer'of improved construction that will afford the greatest freedom of flow and yet be efiective and easily operated to remove the refuse caught by the strainer and to that end a casing is provided having a main straightway conduit for the flow of the fluid and a plurality of chambers opening into said conduit, each of said chambers being provided with a strainer movable independently into SitlClCOIlClLIlt with means to close each of said chambers when occupied by a strainer.

A further object is to provide improved means of moving the strainer elements to and from said conduit and chambers and to close said chambers when occupied by the strainer elements and further to provide improved means for removing the idle strainer for cleaning and repairs.

WVith these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the accompanying drawings Figure 1 is a longitudinal section of a strainer embodying my invention. Fi 2'is a section on the line X-X of Fig. 1. Fig. 3 is a section on the line YY of Fig. 1 and Fig. 1 is a section on the line ZZ of Fig. 1. I

7 Like numerals represent the same parts in the several views.

In the drawings 1 represents a casing forming a straightway conduit 2 having flanges 3 to secure it to the pipe line into which it is to be installed. At one side of said conduit and preferably cast integrally therewith'assliown, the casing 1 is extended to form a plurality of chambers 4, two being shown arranged parallel with each other and opening into said conduit- For convenience in manufacture a head 5 is preferably formed separate from said casing 1 and removably secured thereto by bolts 6.

A strainer basket 7 is provided for each of said chambers and is carried in a frame having a head 8 with projecting rack bars 9' and a ring 10, a latch 11 pivoted to turn on a bolt 12 being provided to secure the basket within the frame. The head 8 of the frame is adapted to move against a seat 13 and acts as a valve to prevent the fluid flowing into the chamber. A supporting guide 14 is provided on which said head or valve moves into said conduit the ring 10' forming the other end of the rame moving on the inner walls of the chamber. The strainer baskets 7 are formed with longitudinally extending recesses 15 adapted tofit projections'of like shape formed on the rack bars 9, to guide and keep the baskets from turning in the frame.

Shafts 16 disposed in longitudinal recesses of the casing and journaled in the walls thereof as shown are provided with worm gears 17 adapted to mesh with the rack bars 9. Independently removable heads 18 are provided for each chamber, said heads being shown secured in place by bolts 19 through slots 20 insaid heads. Bevel gears'21 are journaled in projections 22 of each of the heads and are provided with square holes into which squared end=16 of the shafts 16 project. Shafts 23journaled in' each of the heads and in projections 24 thereof have fixed thereon bevel gears 25 adapted to mesh with the gears 21. A hand-wheel 26 is provided to operate said shaft and gears and a stufling box 27 prevents leakage fromthe head.

A pipe connection 28 is provided with a valve 29, the opening'of which will equalize the pressure in the chambers to permit of the easy movement of the strainer.

It will be seenthat by turning the handwheel' on any one of the heads 18 the bevel and worm gears and racks are operated to move the strainer into'the conduit and that by reversing the operation the strainer is moved into a chamber, the head or valve 8 of the strainer frame seating itself and pre- I venting the flow of the fluid into a chamber when occupied by a strainer. The head- 18 of the chamber occupied by the idle-strainer can be easilyremoved and the strainer taken out for cleaning or repairs. The handle 30 on the strainer isprovided for the" easy Having thus described my invention, I
